I'm looking for a tutor who can help me get a headstart in sketching. It seems that my two options are professional artists who are versed in analytic sketching but who have a more more formal, "classic" way of drawing products and concepts, or ID students who offer to teach ID sketching on the side.

I would focus on learning from either design students, or from resources you can find online. There are a lot of sites/instagram folks/facebook groups focused on design sketching.

Design sketching is fundamentally different from anything taught to classic art students - because it's about rapid communication beyond just rendering form.

With that said, once you understand the difference, I'm sure traditional art classes could help you develop your understanding of form/light and shading beyond that point. I know for myself, art was a standard part of our pre-college curriculum so coming into ID with a foundational background is also important.

Also me looking for industrial design.I have graduated from engineering andindustrial design but recently Ive spentmore in engineering field and I dont wannalose my sketching skills. Would be greatif you know somebody who could teach me more in industrial design!
